Concrete may be hard, but it can’t deal with tension that well, this is why we add rebar to it, it makes it able to deal with enough tension that it gets useful as a building material.
The same principle would apply to pillows, pillows are soft and squishy, put them in a vacuum bag and suck out the air, and you wiuld have a pillow and a plastic bag turned into a sort of a brick.
In construction we modify the raw materials to fit the purpose we need them to.
